While we're on the subject, can someone please add uthread_sigwait
to Makefile.inc in lib/libc_r/uthread? I've been wanting this for
a while; the GNAT port needs this to work. The code is there, it's
just that the function isn't included in the make.

One last question. The other GNAT targets (Linux, Open/VMS,
RTEMS, etc) all seem to want the errno to be _returned_ by
pthread_cond_timedwait (and a couple of others too). This
seems wrong, -1 should be returned, and the error code should
be retrieved from the thread-safe errno. What does the POSIX
spec say about the return value of pthread_cond_timedwait()?
